MAF Map (See Figure 33)
The “MAF Map” is used to alter the MAF signal to the factory ECU. Like the
“Ignition Map”, the “MAF Map” load is based on MAP, MAF, or TPS. The load input is
selected from the
“MAF” section of the “Setup” window. The “MAF Map” has two
different operating modes, Percent and Voltage. The mode is also selected in the
“MAF”
section of the “Setup” window.
 “Percent” mode - The F/IC will measure the input voltage on the MAF input wire
and modify the output voltage by the value in the
“MAF Map”. For an input
voltage of 1 volt, a cell value of 6, the output voltage will be 1.06 volts.
 “Voltage” mode - The F/IC will output the voltage value that is in the “MAF Map”.
For example, the F/IC will output 2.5 volts for a value of 2.5 in the
“MAF Map”.
